Using attack and damage rolls against a level 18 party. How acceptable is it?
Kinda the title. My players are going up against a fairly competentcy caster soon and I was contemplating using attack and damage rolls against them in the fight. I've been worried about introducing them into the game because the internet says its bad to do that to PCs. The party is a monk, sorcerer and cleric. How acceptable is this? Thoughts?
